OIL- -STOVE.

SPECIFICATION forming part Of Letters Patent NO. 422,758, dated March 4,1890.

Application filed March 26, 1889. Serial No. 304,785. (No model.)

To all whom it may concern:

Be it known that I, EDWARD B. FINCH, of the city, county and State ofNew York, have invented a new and Improved Oil-Stove, of which thefollowing is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional elevation of my i1n-' proved oil-stove, taken onthe line 00 0c of Fig. 2. Fig. 2 is a similar view taken on the line y yof Fig. 1. Fig. 3 is a sectional plan view on line .2 2 of Fig. 1. Fig.4 is a plan view of the stove with the covers and cover-supportsremoved; and Fig. 5 is a sectional plan view 011 line z a, Fig. 1,showing a modification.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

The baseA is provided with the oil-tank B in the usual manner. The tankB is made smaller than the interior of the base A to form thesurrounding air-space a. In the top of the tank B are fitted thewick-tubes (J, and upon the base A is placed the casting D, the skirt (1of which rests upon the base A. Between the lower edge of the skirt andthe base A is left-a small space m, which lessens the liability of thebase to become heated. The skirt d of the casting D forms a chamber d,communicating with the space a, surrounding the tanks B, and the top (:1of the casting D is elevated somewhat above the lower edges of the skirtd to leaves spaces between it and the top of the tank for thescrew-boxes c e, and said top (1" is slotted, as shown at (1 for thepassage of the wick-tubes O, and about these slots the said top (i isupturned, as shown at (1, so that the air entering the space a andchamber CZ to the wicks will be deflected against the wick-tubes forkeeping the same cool and for warming the air. Near the skirt d thebottom of the cast ing D is opened or formed with the holes f, throughwhich air from the chamber 01' passes to the body E of the stove, whichrests upon the casting D, as shown clearly in the draw ings, and aflange f is formed within the openings f to prevent the air from beingdo burning 'Air freely enters these chambers through openings g g at thebottom and rises up through the chambers and passes out the openings g gat the top of the body E. This air so passing up through the chambers 9prevents radiation of heat from the combustionchamber, and it becomesheated and rises to the body F, or working part of the stove, where itis utilized or saved. The interior of the body E is divided intocompartments by the partitions G H, which form combustion chambers G Gand H H and the central air-flue J. Air enters the flueJ through a se=ries of openings j in the bottom j of the body E and the correspondingopenings j in the top of the casting D, and passes up through the saidflue and issues in a heated state at the opening 7' into the workingpart of the stove. In each chamber G G H H is placed a burner, so thateach'chamber forms a chimney to its respective wick, and in this man nerany one or all of the wicks may be lighted, as desired, and thecombustion will be per= fect whether one or all be lighted.

In Fig. 5, in addition to the single central air-flue, J, the body isformed with spaced transverse partitions m m, forming flues M betweenthe burners. Air enters these tines through openings m at the bottom,and cor responding openings are formed at the top, the same as intllfsChitlIlbGl J, for the hot air to issue to the working parts of thestove.

By constructing the lower part of the stove as described, with theairspace a, and chamber d, the most of the air to support combustionmust enter at the bottom of the base A, and it is thus brought incontact first with the bottom and sides of the oil tank B, then with thetop thereof, and it'passes thence to the wick-tubes, and thence upthrough. the

chambers g to the working part F. In this manner the oil-tank is keptcool and the radiation of heat to the external air is lessened, and theheat which would otherwise be lost by radiation is carried tothe'working part of the stove and utilized, and by the use of thetransverse air-chanibers between the burners the air that rises from thebottom up through the stove becomes heated in said chambers, and,issuing into the working part of the stove, the heat is utilized, andthese air-chambers are of special advantage when only one or a part ofthe burners are lighted, as the radiation and loss of heat at the sideor sides of the lighted burner is obviated.

Having thus described my invention, What claim as new, and desire tosecure by Letters Patent, is

1. The base A and casting D, mounted thereon and formed with the chamberd and openings f at the top of said chamber, in combination with thebody E, having chambers g and openings g 9 coincident With the openingsf, substantially as and for the pur= poses described.

2. The body E, formed ofan inner and outer Wall spaced to form a chamberg,'the i latter having openings 9 at the bottom and 1 openings at thetop, in combination with outer wall spaced to form a surrounding chamberg, the latter having openings g at the bottom and openings g at the top,and

;, the transverse partitions between the burners,

the adjacent partitions G H forming a chamberJ, having openings at thetop and bottom, in combination with the base A and casting 1D, restingthereon and supporting the body E, and formed with chamber d andopenings 'fj to correspond to openings g j in the body E, substantiallyas described;
